HPLC of Formula: 150-19-6In 2020 ,《Enantioselective Synthesis of Tertiary α,α-Diaryl Carbonyl Compounds Using Chiral N,N’-Dioxides under Umpolung Conditions》 was published in Organic Letters. The article was written by Um, Tae-Woong; Lee, Girim; Shin, Seunghoon. The article contains the following contents:

Bronsted acid-catalyzed addition of the chiral N,N’-dioxide into ynamides generated enolonium ions in situ which underwent enantioselective alkylation by indoles, pyrroles, and phenols, without racemization of the formed tertiary center. This external oxidant approach allows for the use of unmodified nucleophiles and does not leave trace groups from the oxidant, which significantly increases the synthetic efficiency and the product diversity. Furthermore, the byproduct of the N,N’-dioxide could be efficiently recycled into an optically pure form. The results came from multiple reactions, including the reaction of m-Methoxyphenol(cas: 150-19-6HPLC of Formula: 150-19-6)

m-Methoxyphenol(cas: 150-19-6) may be used as an analytical standard for the determination of the analyte in wine, coffee beans, wood samples, and mainstream smoke by gas chromatography (GC) based techniques.HPLC of Formula: 150-19-6

Afailal, Zainab; Gil-Lalaguna, Noemi; Torrijos, Maria Teresa; Gonzalo, Alberto; Arauzo, Jesus; Sanchez, Jose Luis published their research in Energy & Fuels in 2021. The article was titled 《Antioxidant Additives Produced from Argan Shell Lignin Depolymerization》.Computed Properties of C7H8O2 The article contains the following contents:

The present work summarizes the results of an exptl. study focused on producing antioxidant additives for biofuels from argan shell lignin. The generation of this waste has noticeably increased in specific regions of Morocco as a result of the upward trend in the production of argan oil. Lignin extracted from argan shells via a semi-chem. pulping process was depolymerized under hydrothermal conditions in a stirred autoclave reactor at a temperature range of 250-350°C. Lignin conversion to phenolic compounds was conducted in subcritical water together with different reaction medium (H2, CO2, and HCOOH). The organic fraction in the aqueous liquid product was extracted and blended with biodiesel at a dosage of 1 wt % to evaluate its antioxidant potential. According to the obtained results, the biodiesel oxidation stability time was drastically improved up to 400%. The depolymerization temperature was observed as a critical factor in the antioxidant potential of the additives, showing a maximum value at 300°C, regardless of the reaction medium. An extensive characterization of the produced additives was performed. The phenolic monomers present in the produced additives were identified using gas chromatog.-mass spectrometry, finding a notable presence of catechol, especially in the additives obtained at 300°C, which led to the best results of biodiesel oxidation stability. Gel permeation chromatog. analyses of the additives also showed a well dissolution of relatively big mols. (up to 7000 Da) in biodiesel. More efforts are required to verify the actual antioxidant potential of these types of mols. The experimental part of the paper was very detailed, including the reaction process of m-Methoxyphenol(cas: 150-19-6Computed Properties of C7H8O2)

In 2022,Wu, Kai; Yang, Ke; Wang, Siyu; Yu, Jiajun; Chu, Chenyang; Luo, Bingbing; Zhang, Huiyan published an article in Bioresource Technology. The title of the article was 《The enrichment of sugars and phenols from fast pyrolysis of bamboo via ethanol-Fenton pretreatment》.Quality Control of m-Methoxyphenol The author mentioned the following in the article:

The high-purity compounds (e.g., sugars and phenols) are important raw materials and chems., which can be produced by biomass pyrolysis. However, the direct biomass pyrolysis produces complex compounds and thus inhibiting its large-scale utilization. To increase the yield and enrichment of sugars and phenols, a green coupling process based on ethanol-Fenton pretreatment combined with fast pyrolysis is firstly proposed. The bamboo was effectively separated into the ethanol-Fenton pretreated bamboo (EF-bamboo), lignin-rich fractions, and hemicellulose-degradation intermixts. with the massive removal of inorganic metals via this process. Compared with the fast pyrolysis of raw bamboo, the levoglucosan yield of EF-bamboo increased 5.4 times and the enrichment of sugars improved from 7.6% to 59.7%. Similarly, the yield of monophenols from lignin-rich fractions increased around 0.6 times and the enrichment of monophenols increased from 25.7% to 63.5%. This work provides a green and efficient route to produce high-yield and high-enrichment sugars and phenols. In the experiment, the researchers used many compounds, for example, m-Methoxyphenol(cas: 150-19-6Quality Control of m-Methoxyphenol)

In 2022,Rather, Ishfaq Ahmad; Ali, Rashid published an article in ACS Omega. The title of the article was 《An Efficient and Versatile Deep Eutectic Solvent-Mediated Green Method for the Synthesis of Functionalized Coumarins》.Application of 150-19-6 The author mentioned the following in the article:

Herein, we report a green and efficient synthetic route for the construction of diverse functionalized coumarins in good-to-excellent yields (60-98%) via the Pechmann condensation. The optimized synthetic route involves a biodegradable, reusable, and inexpensive deep eutectic solvent (DES) of choline chloride and L-(+)-tartaric acid in a ratio of 1:2 at 110°C. Interestingly, phloroglucinol and Et acetoacetate, upon reaction, furnished the functionalized coumarin (I) in 98% yield within 10 min. On the other front, the same DES at relatively lower reaction temperature (90°C) was found to provide the bis-coumarins in decent yields (81-97%) within 20-45 min. Moreover, this particular method was found to be quite effective for large-scale coumarin synthesis without noteworthy reduction in the yields of the desired products. Noticeably, in this versatile approach, the DES plays a dual role as solvent as well as catalyst, and it was effectively recycled and reused four times with no significant drop-down in the yield of the product.

《Ni-Catalyzed reductive amination of phenols with ammonia or amines into cyclohexylamines》 was written by Cuypers, Thomas; Morias, Thomas; Windels, Simon; Marquez, Carlos; Van Goethem, Cedric; Vankelecom, Ivo; De Vos, Dirk E.. Computed Properties of C7H8O2 And the article was included in Green Chemistry in 2020. The article conveys some information:

Phenol and its derivatives, which naturally occur in lignocellulose, can be considered as a renewable feedstock not only for aromatic, but also for alicyclic compounds, such as primary and N-substituted cyclohexylamines. So far, the latter are mostly produced from non-renewable starting materials like benzene via problematic nitration/reduction or cross-coupling routes. Herein, an efficient reductive amination of phenol with ammonia or amines is demonstrated, for the first time without the need for rare and expensive noble metals and without using any additives. Various supported Ni catalysts were screened and we elucidated the influence of the key parameters, including the acid-base properties of the supporting material. Acquired knowledge was then applied to different phenol-ammonia/amine combinations, resulting in the synthesis of various primary, secondary and tertiary cyclohexylamines in fair to very high yields. In addition to this study using m-Methoxyphenol, there are many other studies that have used m-Methoxyphenol(cas: 150-19-6Computed Properties of C7H8O2) was used in this study.
